INSULAToR-BRACKET. i

T o all wh om t may-amera Be it known thatfl, VARREN B. SIMPsoN,

a resident of Huntingdon, county ofr Hunt ingdon," andV State of z Pennsylvania, have invented-'certain new and useful Improvements in Insulator-Brackets, of whichthe follow-v inv is a specification. j

' yinvention relates to insulator brackets and more l.especially -to that type which is adapted ftobe secured to the top or V'roof of apool for carrying the wires. I

Y The obj ect -of my invention istofconstruct a bracket of the character `above indicated whichis most simple in construction-and at the sameV time having' great strength andi rigidity, ease of securingthe same vto the pole, and cost vof 'production rreduced' to a minimum.

A further object of the invention is to construct and arrange the' parts of the 7 bracket so that the rwires supported by the bracket are close tofthe line of the bolt holes or fastening means, thereby Vfurther assiste' ing inpreserving the lshape of the bracket and its adjusted position under all conditionsof use andweat-her after being secured to the pole.

Another object of the invention is to form and arrange the portion of the bracket inv contact with the pole to be easily and quickly placed in proper position on the top of a pole and at the same time permit the bracket to readily adjust itself to the langle of the roof of the pole top while being fastened or secured thereto.

Other objects and advantages of the invention will appear from the detailed de-4 In the drawings l0 and 11 represent two' sections of metal preferably of channel iron form and made of different lengths, the section 10 as shown being shorter than 11. Said sections 10 and 11 are bent at an angle and Appucation mednovember 25, 1919. serial 110.340.452.

Specification of Letters Patent; PatentedY gether by rivets 12 orother suitable means so as to form an upright cen'trallstandardll' and two loppositelyV disposed and :diverging sections 14 and 15 which'lform'preferably' a right angle with'each `other 'as illustrated.

The-outer ends 16 and 17 of saidsections 141 and 15 'are turnedor bent' upwardly toward thestandard 18 Vandarranged parallelwith` the Y'same for purposes to be presentlydescribed. The longer section- 11 extends above and beyond theupper endofthe short-` section 10 to form an upper reduced end 18. Eachy of the outer ends 16 and 17 and Yupper reduced end'lS are-provided with any oneofv the commonly uscdattach'mentsormeans 2O of fastening insulators lI to ithe bracket.y

Each of the divergingl sections 14e and 15 has one onmore holes'21, drilled in the web portion of the channel through -which Ilag bolts 22 or other fastening devices are passed if 1 to `firmly and'rigidly secure the bracket to the top of Vafpole P which has had its top roofed off 1asis usual 'in poles designed `for supporting and Ycarrying electric conductors j v pole corresponds to the angle between the l diverging sections 14: and 15 of the bracket.

From the foregoing disclosure of con-v struction and arrangement vof the parts of the invention it will be seen that the bracket consists primarily and essentially of only two simple elements 10 and 11 which are capable, owing to their channel cross-sections,

.of not only rigidly supporting the weight of the electric conductors but also at the Sametime resisting anyfstrains in the'direcf tions parallel to the lengthvof the electric conductors supported by the bracket, or any angle thereto. Furthermore the diverging sections 14 or 15 of the bracket coming in Contact and secured to the top of the pole readily adapt themselves tothe angle of the pole top while being screwed or forced down on the pole, thereby insuring a maximum resistance against any movement what-l soever. The two simple elements 10 and 11 of the bracket also enable these-conductors to be supported as near as possible to the points of attachment of the bracket and hence reduces to a minimum the lever armsY of the forces acting in the conductors from Y the points of attachment of the bracket and hence the factor of safety in preventing the bracket from being detached from the pole or its shape distorted is a maximum, conlio sidering the number of elements and amount of metal employed in the manufacture of said bracket. The provision of having one section 11 longer than section 10 enables me to readily without any further machining' efliciently carryY out yall the functions and advantages pointed out in the -statement of the invention, and it will be readily understood that various minor changes in the specie-details of construction can be resorted to withinthe scope of the claims without departing from, or sacricing any of the advantages of the present invention. l

What I claim is Y 1. An insulator bracket to be secured to the top of a pole comprising two sections of channel jiron of unequal length bent at' an angle and connected together at a portion of the back of their web lengths to form a central upright standard provided with means on the outer end of the longer section for engaging aninsulator, the disconnected portions of the two sectionsl divergingfrom each other and so constructed, arranged and adapted to have the back of their web lengths to be seated and secured to the top of a pole and provided at each of their oppositely disposed ends with means for engaging an insulator.

2. An insulator bracket of substantially anchor shape comprising two sections of Vchannel iron bent at an angle and arranged 3; An insulator bracket of substantially' anchor shape comprising two sections of channel iron ofunequal length bent at an angle and arranged backV to back and connected together at a portion of their lengths to form a central upright standard having means on the outer end of the longer section t'or engaging an insulator, the disconnected portions of the two sections diverging from each other and so constructed, .arranged and ladapted to permit the web sections of the channels to be seated and secured to the topf of a pole and provided at veach of their ends with means for engaging an insulator.

In testimony whereof I affix my signature.
